The terylene polishing fiber can be used for removing abrasive dust and polishing objects easily, can be used for polishing unevenness surfaces with excellent effect, and is capable of taking a portion of the effects of emery cloth, sand paper, rag, cotton yarn, abrasive paste and polishing agent; and polishing effect and heat dissipation effect are excellent.

Description

A kind of terylene polishing silk and production method thereof

technical field

The invention belongs to polishing field, be specially a kind of terylene polishing silk and production method thereof.

Background technology

Along with the development of each fermentation of society, the raising of people's life, the article such as the article that use, machine, not only want practical, also want beautiful good-looking simultaneously, so increasing product will carry out polishing for its surface, in use for some time, user oneself also will carry out manual grinding and polishing to it and process the article that even have, and allows article reach constantly noble, beautiful state.In hand lapping, polishing, traditional instrument is sand paper, emery cloth, but the grinding of sand paper, emery cloth, polishing effect have some shortcomings, for example: polishing light decorations effect is bad, abrasive dust is difficult for getting rid of, it is bad to dispel the heat, service life is not long, be difficult to process rough surface etc.

Terylene is the trade name of the important kind ，Shi of in synthetic fiber China polyester fiber.It is to take fiber-forming polymer---the polyethylene terephthalate (PET) that p-phthalic acid (PTA) or dimethyl terephthalate (DMT) (DMT) and ethylene glycol (EG) make through esterification or ester exchange and polycondensation reaction as raw material, the fiber of making through spinning and post processing.

Polyster fibre has fluffy, plentiful, soft style, and has the feel of wool, usually as cloth, fabric.Polyster fibre silk has that intensity is high, good springiness, terylene smooth surface, and interior molecules is arranged closely, ABRASION RESISTANCE is good, light resistance, corrosion-resistant etc. advantage.

The present invention is when producing polyster fibre silk, add brown fused alumina micropowder, make the polyster fibre silk produced, there is the function of polishing, the polishing function that can replace sand paper, emery cloth, abrasive pastes, polishing agent, to make up some shortcomings of sand paper, emery cloth, abrasive pastes, polishing agent.

Summary of the invention

The production technology of polyster fibre silk is very ripe, cost of material is cheap, and the filament of producing is fluffy, soft.Palm fibre corundum is that in all abrasive materials, toughness is best, is blended in polyster fibre silk, with respect to other abrasive material, has good effect.Raw material and the brown fused alumina micropowder of making polyster fibre silk are evenly mixed in proportion, with production technology and the device fabrication of producing polyster fibre silk, go out terylene polishing silk.

Technology path of the present invention.

A polishing silk, by raw materials used weight ratio, comprising: (1) polyethylene terephthalate (PET) 90-99%, (2) brown corundum 0.9-9.6%, (3) calcium stearate 0.1-0.4%.

A kind of production method of terylene polishing silk:

The first step, polyethylene terephthalate (PET) 90-99%, Celsius 140 degree under, under vacuum condition, be dried;

Second step, keeps 140 degree temperature Celsius, adds 0.1-0.4% calcium stearate under normal pressure, mixes;

The 3rd step, adds the brown fused alumina micropowder of 0.9-9.6%, mixes;

The 4th step, mixture melt extrudes through screw rod, through spinnerets ejection spinning, coiling, obtains spun filament;

The 5th step, balance, by stretching, curling, relaxation heat setting, obtains polishing filament.

Brown fused alumina micropowder number is 1000-2000# granularity, the melt temperature melt extruding is 280 degree Celsius, melt viscosity is 0.55dl/g, spinning ring blowing temperature is 15 degree Celsius, and wind speed is 1m/s, and cabinet temperature is 30 degree Celsius, winding speed is 1137m/min, spinneret draft ratio is 145, and the temperature of stretching is 28 degree Celsius, and relaxation heat setting temperature is 60 degree Celsius.

Beneficial effect of the present invention

1. terylene polishing filament is easy to get rid of abrasive dust after using neutralization to use;

2. with terylene polishing filament polishing article, light decorations effect is very good;

3. because space between terylene thread and terylene thread is sufficient, so good heat dissipation effect;

4. abrasive particle difficult drop-off, long service life;

5. because terylene polishing silk has fluffy, plentiful, soft character, the rough surface of polishing, effect is remarkable;

6. can replace the part effect of emery cloth, sand paper, rag, cotton yarn, abrasive pastes, polishing agent.

The specific embodiment

Below in conjunction with embodiment, the present invention is described further.

By brown corundum fine powder, polyethylene terephthalate (PET), calcium stearate 0.3%, in 5%, 94.7%, the ratio of calcium stearate 0.3% prepares burden.Its production stage is as follows:

The first step, (1) polyethylene terephthalate (PET) 94.7%, Celsius 140 degree under, under vacuum condition, be dried;

Second step, keeps 140 degree temperature Celsius, adds 0.3% calcium stearate under normal pressure, mixes;

The 3rd step, adds 5% brown fused alumina micropowder, mixes;

The 4th step, mixture melt extrudes through screw rod, through spinnerets ejection spinning, coiling, obtains spun filament;

The 5th step, balance, by stretching, curling, relaxation heat setting, obtains terylene polishing filament.

Brown fused alumina micropowder number is 2000# granularity, the melt temperature melt extruding is 280 degree Celsius, melt viscosity is 0.55dl/g, spinning ring blowing temperature is 15 degree Celsius, and wind speed is 1m/s, and cabinet temperature is 30 degree Celsius, winding speed is 1137m/min, spinneret draft ratio is 145, and the temperature of stretching is 28 degree Celsius, and relaxation heat setting temperature is 60 degree Celsius.
